SAW-SET.

Speccation of Letters Patent.

Patented Sept. 18, 1906.

Apiicaion nea May 4., 1906. semi No. 315,222.

To all whom it may concern:

Be it known that I, CLARENCE CLEAv- LAND BEARD, a citizen of the United States, residing at Sailes, in Bienville parish and State of Louisiana, have invented certain new and useful Improvements in Saw-Sets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in saw-setting tools, and it relates more particularly to that class of saw-sets which is especially designed for use in setting the teeth of crosscut-saws.

The invention has for its object a general improvement in this class of devices and the provision of a simple and inexpensive sawsetting tool by the use of which it would be possible to readily and accurately set sawteeth.

To this end, and such others as the invention may pertain, the same consists in the peculiar construction of the device and in the novel arrangement, combination, and adaptation of parts, all as will be more fully hereinafter described, shown in the accompanying drawings, and then specifically deiined in the appended claim.

The invention is clearly illustrated in the accompanying drawings, which, with the letn ters of reference marked thereon, form a part of this specification, and in which- Figure 1 is a perspective view of the device, the same being shown as applied to the tooth of a crosscut-saw. Fig. 2 is a vertical section upon line 2 2 of Fig. 1, and Fig. 3 is an enlarged detail in perspective of the swageblock.

Reference now being had to 'the details of the drawings by letter, A designates the sawset, the same comprising a shank or body por tion B, having secured upon one of its sides at its lower end the metallic plate C, the said plate being held by means of transverse bolts D, being provided at the outer ends with thumb-nuts D. The inner face on the lower end of the body portion B of the device is cut away to form a recess between the said body portion at the lower end of the plate C to receive the saw-teeth, a shoulder E being provided at a point slightly above the vertical center of said slot.

F is a metallic swage-block, consisting of a solid piece of metal sufficiently rectangular in form and having rprovided upon one of its faces at a point a short distance above its longitudinal center an angular projection or rib F, extending transversely across the face of the block. The rear surface or face of the block F is Hat and designed to have a bearing against the inner face of the plate C within the recess formed between the said plate and the lower end of the slot designated to receive the saw-teeth and is connected with the said plate C by means of pins I, which said pins are carried by the block F and are movable within the openings formed in the said plate C.

J is a set-screw passed through a screwthreaded aperture provided in the plate C at a point opposite the shoulder E, the office of which is to cause the projection or rib F upon the block F to form the set to the end of a tooth by forcing the same against the inclined shoulder E.

From the foregoing description the operation of the device will be readily understood. The slotted lower end of the device is passed over the saw-tooth to be operated upon, as shown in Figs, l and 2. The point of the tooth which is to be set is brought into contact with the shoulder E by the adjustment of the set-screw J and it will be noted that when thus in position the point of the tooth to be operated upon is clamped or held between the shoulder E andthe shoulder F upon the inner face of the swage-block upon the opposite side of the slot, being held in place by the tightening of the thumb-screw J. When thus held in position, the point of the tooth is set by a blow imparted by a hammer to the upper end of the device, the shoulder E and rib F upon opposite sides of the saw-tooth insuring the accurate and uniform setting of the teeth of the saw. It will of course only be necessary to change the adjustment of the swage-block in order to accommodate the varying thicknesses of the saws operated upon.

Having thus described my invention, what I claim to be new, and desire to secure by Letters Patent, is-

A saw-setting device comprising a bar having a recess upon one face thereof, a plate IOO provided with a recess upon its inner face and fixed to said har, a pin passing through the lower end of said plate, a swage-hlock loosely mounted upon said pin and provided with an angled rlo upon the face thereof 0pposte an inclined shoulder upon the side wall of the recess in said bar, a set-screw carried' by said plate and adapted to bear against said swage-hlock, and a second set-screw carried by the bar and adapted to bear against a ro saw-tooth held within the recess7 as set forth.

In testimony whereof I hereunto ax my signature in the presence of two witnesses.
